3 Claims. l

The present invention relates to auxiliary windows of the type usually referred to as storm windows, and particularly to that type of construction in which an auxiliary frame is semi permanently installed in the standard window frame of a building, and is so constructed as tc accommodate a pair of superposed, independently movable sashes. Either or both of such sashes may carry glass or screen, and the construction of the auxiliary frame is such as to permit re moval of a glass-carrying sash and substitution of'a screen-carrying sash therefor.

The primary object of the present invention is to provide a device of the character described so designed that it may feasibly be constructed substantially entirely of metal, whereby its life and efficiency will be substantially increased. VFurther Objects of the invention are 'to improve details of such constructions, to the end that the entireV a'ssemblage may be more emcient and satisfactory than previously known devices of the vsameV general character. Still further objects 'of the in vention will appear as the description proceeds.

To the accomplishment of the above and related objects, our invention may be embodied in the forms illustrated in the accompanying draW'- ings, attention being called to the fact, however, that the drawings are illustrative only, andthat change may be made in the specic constructions illustrated and described, so long as thescopeoi the appended claims is not violated.

Fig. 8 is an enlarged fragmental perspective View of a latch, and associated parts. forming a part of the present invention; and Y Fig. 9 is a view similar to Figs. 6 and '1, but showing an auxiliary adapter element associated with the previously illustrated parts.

Referring more particularly to the drawings, it will be seen that we have shown a standardwindow frame formed to provide guidewaysZt for standard window sashes (not shown); the construction including an outside frame, indicated generally by the reference numeral 2| and an inside frame indicated generally by the reference numeral-22, each of said frames including a top member, tworside members, and a common sill 23 inclining downwardly toward the outside wall 24 of the building. Our auxiliary frame construction is indicated generally by the reference numeral 25, and is preferably supported between the sill 23 and the top member of the outside frame 2|, in the manner clearly illustrated in Fig. v3.

The reference numeral 26 indicates generally an auxiliary frame which comprises a top member 21, two parallel side members 28 and 29 and a bottom member 3U, said members being suitably joined to produce a reasonably vrigid supporting frame for the sashes later to be described. The top member 21 is formed, at its edge facing the interior of the frame, with parallel iianges 3l and 32 dening an inwardly opening groove guideway section 33 of substantial depth. In its outer edge, said member 2l is formed with a dovetail'groove 34, extending substantially through-- out the length of said member, and opening outwardly. A plurality of longitudinally spaced bores 35 penetrate the diaphragm between the guideway 33 and the groove 34 :for the reception of screws 36 whereby said member 2l may be secured to the top member of the window trarne 2l. Anadapter 3'! is secured alsov to 'said frame member 2! by a plurality of screws 3d, and is formed with a downturned flange which overlies the outer surface of the'member 2 to sealany space which maylexist between the member 2 and the' frame member 2l, against drafts' and moisture;

The side members 28 and 29 are allochirally related, and therefore only one of said members is described in detail. The member 28 is formed, at its longitudinal edge facing toward the interior of the frame 26, with parallel flanges 35 and 4G defining a guideway or groove 4i which extends substantially throughout the length of said member. In its opposite edge, said member 28 is formed with an outwardly opening dovetail groove or channel 42 which likewise extends substantially throughout the length of said member; and a plurality of longitudinally spaced bores 43 open through the partition between the grooves 4I and 42 for the accommodation of screws 44 whereby said member 28 is secured to the side member of the standard frame 2i. Associated with said side member 28 is a sealing strip, indicated generally by the reference numeral 45, and comprising a head 4G whichA overlaps the outwardly presented face of the member 28 and the substantially coplanar face of the standard frame 2l, to seal any space existing between said members against drafts and moisture. The member 45 comprises also ancintegral stem 41 which is adapted to be positioned between the member 28 and the member 2l and a tail 48, acutely angularly related to the stem 41 upon such an angle that said tail may be received in the channel 42 in snug engagement with that Wall of said dovetail channel adjacent the outwardly presentedl face of the member 28. The construction is such that the member 28 yand the member 45 may be assembled by relative longitudinal sliding movement, but the engagement is reasonably snug so that, once assembled, there will be substantially no relative movement. It may be noted, from an examination of Figs. 6 and '7, that the screws 44 are preferably driven into the window frame 2l at a slight angle to the outwardly presented surface of said frame, whereby the action of said screws tends to tighten the engagement of the head 46 of the sealing strip 45 with the substantially coplanar surfaces of the standard frame and the auxiliary frame.

As will be seen from an inspection of Fig. l, the flanges 40 of the side members 28 and 29 are cut away, as at 49, from a point just slightly below the middle of the frame 26, for a purpose which will later appear.

The bottom member 38 of the auxiliary frame is a composite construction, as is clearly illustrated in Fig. 4. It comprises a base element 58 formed, in its lower edge, with a dovetail groove l adapted to receive a portion 52 of a resiliently deformable strip 53 of water repellent material, such as rubber, the remaining portion 54 of which remains outside said groove and is adapted to bridge the mouth 5I of said groove and to be compressed between the memberV 58 and the sill 23. When material such as rubber is used for the element 53, the portion 52 thereof will be expanded into the dovetail groove 5l by the compression of the portion 54 thereof.

The upper edge of the member 58 is formed to provide a pair of parallel, spaced, upwardly projecting, longitudinally extending fingers 55, 55' which may preferably be resilient and normally slightly divergent. The other element 55 of the bottom member 38 is generally U-shaped to provide spaced fingers 51 and 58 adapted to engage snugly over the fingers 55 and 55 in telescoped relation; and the upper edge of said element 58 is suitably formed, as for instance into the shallow V 59, for cooperation with the bottom member of a sash to be supported in the auxiliary accept? frame. It will be clear that the composite member 3B is adjustable in height, the purpose being to provide for some slight adjustment to compensate for variations in standard window frame heights. The frictional engagement between the nngers 55 and 55 on the one hand and the nngers 51 and 58 on the other hand, will normally be sufficient to maintain the parts 50 and 58 in desired relationship; but in some instances it may be desirable to provide means for clamping or otherwise securing the members 50 and 55 in any selected relative position of adjustment.

A sash frame (see Fig. 1) may Ibe made up of a top member 8l (Fig. 5) a bottom member 62 (Fig. 4) and a pair of allochlral side members 83 (see Fig. 6), suitably connected together to form a reasonably rigid frame. The inwardly facing edge of the top member 8l is provided with a longitudinally extending groove 64 adapted snugly to receiveV the upper edge of a glass pane 55; and the side members 63 are formed with similar grooves 56. The bottom member 62 is formed with a longitudinally extending slot 61 communicating with the grooves G8 and coplanar with the groove 64. The glass pane 65 is assembled in the sash frame, after solid assembly of the frame, by insertion through the slot 61, and by sliding said pane through the lateral grooves 58 until its upper edge is rmly seated in the groove 64, rl`hereafter, an insert 68 (which may preferably be formed of hard rubber, though any other suitable insertable piece or packing material may be used), formed in its upper edge to receive and snugly support the lower-edge of the pane, is entered in the bottom of the slot 61 and secured in place by means of screws 61', or other suitable fastening means.

This construction may be used in any glazed sash, either upper or lower, though it is herein shown only in the upper sash. The bottom member B2 of the sash frame 6B is formed with an inwardly projecting finger ledge or flange 69 substantially perpendicular to the plane of said frame.

Mounted upon the inner surface of the member 28, slightly above the mid-point thereof, is a bracket 18 carrying a spring finger piece 1I formed with a latch nose 12 adapted to engage beneath the flange 59 of the upper sash 60 to support said upper sash in a position in which its top member 6l is sufficiently engaged in its groove 33 to seal against drafts and moisture. It will be noted, however, from an inspection of Fig. 5, that this normal supported position of the frame 80 is one in which the top member 6I is spaced slightly below the base of the groove 33. The reason for this construction will be understood as the description proceeds.

If desired, of course, the latch construction just described may be duplicated upon the frame mem-ber 29; but it is our present belief that such duplication will not be necessary.

A lower sash frame 13 may comprise a top member 14 whose outer edge is suitably formed for sealing engagement with the outer edge of the bottom member 62 of the upper sash frame 50. As illustrated, said upper edge of the member 14 is flatly V-shaped, as at 15, for engagement in a groove 18 formed in the lower edge of the bottom member 62 of the frame B8. Thereby, a draft proof and moisture proof seal is provided between the two sash frames. When the sash frame 13 is in position, it will support the sash frame 6D.

asados? The bottom member 11 of the sash 13 is similarly grooved, as at 18, te form, with the upper edge 5 9 or the member 56, a draft proofv and moisture-proof seal, said sash 4flame 13 normally being supported upon the member 56. Said bottom member 'E1 is iormed with a lip or finger flange l'which projects inwardly substantially perpendicular to the plane, of said frame.. As 1liustrated. a sheet. of screeningllis suitably supported upon the frame 13- any Well known manner.

At longitudinally spaced; points., the member 55 carries, upon its inner surface, two swivel pins 8l. Nuts 82 threadedly mounted on said pins are adapted to clamp in any desired position of adjustment pair of brackets 83. Each of said brackets is substantially Z-shaped comprising a base portion 34 parallel with the plane of the sash frames and pivotally mounted near one corner, upon a pin 8l, a web portion 85 projecting inwardly substantially perpendicular to said plane, and a guard portion 86, substantially parallel with the base portion 84. In the position in which said brackets 83 are illustrated, their base portions 8d project above the apex 59 of the member 55 suliiciently to prevent inward swinging movement of the bottom member 11 of the lower sash frame 13, even after said sash has been raised suiciently to clear the member 56 from the groove 18. If, now, the members 83 are turned upwardly through an angle of 90, their web portions S5 will lie substantially in a horizontal plane with said apex portion 59 of the member 56. Because of the clearance between the top member 'el of the upper sash 60 and the base of the groove 33, the two sashes may now be raised slightly, by lifting upon the lip 19, to clear the member 56 from the groove 18. Because of the out away portions 43 of the flanges 40 of the side members 28 and 29, an inward pull upon the lip 79 will cause the sash to swing about its upper edge as a hinge, said upper edge being held against inward movement by the projecting portions of the anges 49; and the bottom member 11 of the lower sash frame 13 may be brought to rest upon the web portions 85 of the brackets 83, being limited in its inward movement |by the portions 83 of said brackets. This position of the parts is desirable, of course, only in the winter when the lower sash frame, as well as the upper sash frame, will carry a glass pane.

On the other hand, if the brackets 83 are turned downwardly 90 from their illustrated positions, the whole of said brackets will be disposed below the horizontal plane including the apex of the member 56. With the brackets in that position, when the lip 19 is lifted and pulled inwardly, the sash 13 can be swung far enough inwardly to permit its bodily extraction from the frame 26. As the sash 13 is withdrawn from the frame, the sash BIJ will come to rest upon the nose 12 of the latch 1l. frame like the frame 13 may be introduced into the organization, if desired.

On the other hand, if it is desired to do so, after removal of the sash 13, the nose 12 of the latch 1l may be withdrawn from engagement beneath the lip 59, whereupon the sash 60 may be lowered into the position previously occupied by the sash 13, and may be withdrawn from the assembly in the manner above described. The function of the latch 1I of course, is to support the sash 60 at times when the sash 13 Ais not in position to support said sash 60.

In Fig. 9, we have shown the frame member Now a substitute sash 6 28 associated with an adapter 90'. Occasionally,- an outsize window frame may be encountered; and when that occurs, the provision of the dovetail slots in the elements of the frame 26 makes it possiblevto associate therewith one or more adapters like the element 90. The adapter comprises a metallic bar formed, in one edge, with a dovetail groove 9| identical with the dovetail groove 42. At its opposite edge, the bar 90 is formed with a pair of diverging ngers or flanges 92, the angle of flare of said fingers being identical with the angle of flare oi. the groove or channel 42. Therefore, the adapter 90 may be assembled with the frame side member '2,8 (.Or with any one of the other members of said frame) by entering the fingers 92 in one end oi the channel 42, and then moving the members 28 and 90 relatively longitudinally. The illustrated construction very rmly secures the two bars t0- gether; and the adapter 90 is formed with a plurality of ports 93 adapted to register with the ports 43 of the side member 28 for the accommodation of screws 44', longer than the screws 44.
